Modelling of a steam line whip and of a whip restraint by SYSTUS programme
Novotný J., Novotný J. jun.
pages 188 - +8p, full text

To model the process of a circumferential crack evolution leading to the pressurized pipe rupture a special element in the programme SYSTUS is used. The stiffness and damping coefficients of this two node element may be defined as dependent on the relative displacement and velocity of its nodes. Such elements are used to model a whip restraint and a viscous GERB damper. Whip of of the steam line and its effect on the steam generator is analyzed. Large deformation and non-linear material properties are taken into account.
